I'm renting a bedroom in a house with shared wifi, and I'd like to secure myself against any network snooping. I know that using the wifi network basically opens me up to snooping of any unencrypted traffic by anybody who knows the PSK. I'd like to use ethernet only, but I have devices that are wifi-only (like my phone).

I want to install a powerline adapter and run it into a gateway router in my room, then use that to establish my own secured wifi connection. My question is, will this work to secure me against any network snooping? The router is placed in a public area, so I can tell if someone sets up a hub between the router and the cable modem. The router is a Linksys router, but I've yet to determine if DD-WRT is set up on it or not.

    @Rory Alsop - I'd argue it's not a duplicate; There is a huge difference between knowing the sites someone has visited vs seeing the traffic for everything they are doing. I don't care if someone knows which banking sites I've visited, I do care if they see the username/passwords/2PA. Oct 3, 2014 at 23:23
  • If youread the linked question you will see it covers off both these instances.

  • So are you trying to secure yourself against the owners of the cable modem and the router, or against other apartment-mates with access to the "public area", or against people who might access the shared open WiFi?

Your best bet for security would be a secure tunnel between the gateway router you will insert into the network and a 'safe' outside point. This could be a server you've rented, or you could use one of many VPN providers who exist.

Of course the 'safety' of said server/VPN provider is variable, but it means any traffic you send via that gateway router will be encrypted until it reaches the end point and anyone viewing it won't be able to see the cleartext.

You could also try routing over something like Tor via your gateway however I have no personal experience with this and can't advise on how useful/suitable it'd be.

Finally you could use a 'secure' proxy service too however most of these of are questionable realiablity (when using 'free' services - I've not used paid services in this regard.).


Put up your own firewall and wifi access point, secured with WPA2, and treat your housemate's network exactly like you would treat the Internet - hostile.

    That does nothing for security once the traffic has left his local network. His housemates could view his unencrypted traffic the same way his ISP can. Oct 3, 2014 at 23:21
  • So? It's exactly as secure as anyone's connection to the Internet. If he thinks his housemates are the only malicious attackers on the Internet that he has to secure himself against, he would be dangerously mistaken. Oct 3, 2014 at 23:54
